GPS maps

[lobo1]

Got a new TOOL for the boat - A Garmin 182C GPS. I put the Bluecharts maps on a memory card for huron/erie/ontario. I was wondering if there was a product out there that would also allow me to put some inland lakes on there like Houghton, Burt, Mullett, Leelanau etc.

any ideas ? :confused:
